To check your cryptocurrency airdrop token balance, follow these steps: First, identify the blockchain network the airdrop tokens are on (e.g., Ethereum, Binance Smart Chain). Next, use a compatible wallet like MetaMask or Trust Wallet that supports the network. Import your wallet using your private key or seed phrase if it’s not already set up. Then, visit a blockchain explorer like Etherscan (for Ethereum) or BscScan (for BSC). Enter your wallet address in the search bar to view your token holdings. Alternatively, some airdrop projects provide a dashboard on their official website where you can connect your wallet to check your balance directly. Always ensure you’re using official links and avoid sharing your private key to stay safe. If the tokens aren’t visible, you may need to manually add the token contract address in your wallet.
